## Quality 88/100 (good)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 300000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: list_origins (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); weekend_prices (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cheapest_weekends (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 1,487 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 3 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 1,487 tokens to load them all

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-13 `weekend_prices` changed (description)
  - before: The next 47 weekends (328 days) for one origin-destination pair, with the cheapest round-trip price per weekend and the time the price was observed ("as_of"). Cached prices answer at once; weekends not priced yet are searched live during the call, the way a page visit searches them (usually 10-40 s, at most ~55 s). If the search does not finish, the answer says which weekends are still open and to call again. Takes every filter the route page has: trip shape (combo), cabin, stops, passengers, departure and return time windows, currency. Free: fri-sun, economy, any stops, any passenger mix, no time window. Pro session cookie: other combos, other cabins, time windows.
  - after: Every weekend of the next 12 months for one origin-destination pair, with the cheapest round-trip price per weekend and the time the price was observed ("as_of"). Cached prices answer at once; weekends not priced yet are searched live during the call, the way a page visit searches them (usually 10-40 s, at most ~55 s).

## Tools (3)

- `cheapest_weekends`: The cheapest weekends from one origin across every destination that has a calendar under these filters, sorted by price. Optional month filter (yyyy-mm). Takes the same filters as weekend_prices. This tool reads what is already priced; it does not search every destination. A destination that is absent can be priced with one weekend_prices call for that pair. Pro only: this tool is Anywhere (every destination from one origin). Without Pro it answers pro_required with the Anywhere page url. One route at a time is free with weekend_prices.
- `list_origins`: Returns the departure airports (IATA) that have at least one priced weekend calendar, with the count of priced destinations per origin. Start here to learn what cheapest_weekends can answer at once. weekend_prices works for any airport pair and searches live when needed.
- `weekend_prices`: Every weekend of the next 12 months for one origin-destination pair, with the cheapest round-trip price per weekend and the time the price was observed ("as_of"). Cached prices answer at once; weekends not priced yet are searched live during the call, the way a page visit searches them (usually 10-40 s, at most ~55 s). If the search does not finish, the answer says which weekends are still open and to call again. Takes every filter the route page has: trip shape (combo), cabin, stops, passengers, departure and return time windows, currency. Free: fri-sun, economy, any stops, any passenger mix, no time window. Pro session cookie: other combos, other cabins, time windows.
